3500 mile trip. Coolant pump failed 1000 miles in.
Harley Davidson builds one tough bike. My cooling system on my 2015 Ultra Limited failed 1000 miles into our round trip ride from Dallas Georgia to Rocky Mountain National Park in Colorado. Either the thermostat or the pump failed. All I know right now is no coolant was flowing through the engine.
Stopped at a Harley dealer in Colorado Springs. Waited 3 hours and they still had not got to my bike yet. They told me I absolutely could not ride with a failed cooling system. I said screw it and rode on. 2500 miles later and still no ill effects other than the bike ran a little hotter than normal. Performance over 12000 ft. mountain peaks and 103 degree temps was normal other than at every stop the ECMS would shut down a cylinder.
Thinking about now having all the “twin cooled” heads removed, replacing with regular heads and an oil cooler. Anyone removed the coolant crap?
I’ll bet no other motorcycle built today could continue to run for 2500 miles with a failed cooling pump or thermostat.

Cooling the exhaust valve was a great idea,the bad is they made it with cheap parts.
Someone on here actually found the problem, appears to be an electrical connection on in the pump body. I would imagine after so many warranty issues they have identified the problem and gone back to the supplier. Just takes time to get the pump out in the supply system. I had read somewhere there is a new updated part number. Thats awesome you rode it with no pump and no issues. After two pumps I have considered doing the same thing, but since they have replace both under warranty I will keep letting them do it until it costs me money.
The water cooling system is in addition to the air and oil cooling that every Harley has always had. Without the water in it, it is just like my non water cooled bike. But there are benefits to it when it works. I would get it fixed.

My wet head '14 Limited definitely does not have an oil cooler.
If you can wrench at all, it takes less then an hour(and one hose clAmp) to change. The dealer wanted 4 hours of labor for diagnostics, the 3 more for install- nope.
Very few dealers around me had one, and its a 7-10 day order time.
Total piece of junk water pump.
How do I know? Changed mine Saturday.
Here is a diagnostic shortcut. Ignition on-engine off. Rotate throttle to 1/2 or more. Fan1 comes on, fan 2 comes on, the water pump comes on. You can remove the shroud, and put your hand on the water pump, and feel it running. (Or not)

I believe he meant that the circulating oil helps cool the engine. It does that oil cooler or not. An oil cooler just increases that cooling effect. Harleys came without oil cooler for years. I think they only started adding them because so many owners added them aftermarket.
